摘要

The axial passage 15 of the central foot (14) of the membrane support (13) has a valve seat (16) which is applied on the end of the hollow rod (5) of the continuous valve in order to fill the bell- shaped metering device (11) during the metering phase, and which moves away from this end of the hollow rod (5) in order to connect the bell- shaped metering device to the joining piece (21) during the expulsion phase.
